Energy-saving optimization control method and device for compressed air industrial system

Abstract

The invention provides an energy saving optimization control method and device for a compressed air industrial system and belongs to the field of compressed air supply and industrial process control. Energy wasting and resource consumption can be reduced. The energy saving optimization control method comprises the steps that the pressure value of main pipes, and the pressure value and the flow value of N branch pipes are obtained through pressure gauges; the filtering pressure value of the multiple sets of main pipes and the filtering pressure value of the multiple sets of N branch pipes are subjected to normalization processing, and the normalized pressure value of the main pipes and the normalized pressure value of the N branch pipes are determined; the stability of the compressed air system is determined through the formula according to the average pressure value of the main pipes in the first time period, the average pressure value of the main pipes in the second time period, the average pressure value of the N branch pipes in the first time period and the average pressure value of the N branch pipes in the second time period; the air source header pipe pressure optimization set value is determined through the formula according to the characteristic coefficients and the pressure target lower limiting value of the N branch pipes; and controlling of the main pipe pressure value is determined.

Description

technical field [0001] The invention belongs to the field of compressed air supply and industrial process control, and more specifically relates to an energy-saving optimization control method and device for a compressed air industrial system. Background technique [0002] A compressed air system is one in which air at atmospheric pressure is compressed and delivered to a pneumatic system at a higher pressure. The compressed air industry includes air compressors (air compressors) for air source equipment, post-processing equipment, air storage tanks, transmission pipe networks, and pneumatic equipment at the end of pipelines. [0003] In the existing pneumatic technology, the pressure setting value of the air compressor is set manually. In order to meet the pressure and flow requirements of the terminal pneumatic equipment, the pressure setting value is often set to a higher setting value for a long time, so that the air compressor The machine is in a high load state for a ...
